Is it a good idea to anneal new brass? Or should I fire it first? It's new winchester brass for 308. I'm going to start load development on a new barrel soon.

Re: Annealing new brass

No need to anneal new brass...It's already been done when produced. Anneal after 3-5 firings.

I wouldnt, unless you are going to fireform it to AI.

I've never needed to do this to fireform AI.

I'm going to wash my truck, then take it to the car wash.

Makes about as much sense.

Not as much as a need, but a should. While most brass will form AI with no problems, some come hard from the factory and can crack at the shoulder. Like Rem and Win brass. Lapua, not so much as it comes soft from the factory.

Re: Annealing new brass

Why does Lapua brass come annealed new? That's what made me think of doing it. Do they use a harder brass or is it because the brass is thicker?

Re: Annealing new brass

All bottlenecked rifle brass is annealed on the shoulder and neck areas after it has been formed. Just most other commercial manufacturers polish it before packaging it.
